鲁达 需求
在一些项目现场，很多时候，都是缺少专门的数据库运维人员的，但是开发人员开发项目，又需要用到MySQL数据库服务器，而且不同的项目的数据库又要分开
项目需求
解决方案
对于非数据库运维人员，安装MySQL数据库有一定的难度，所以在这里推荐用docker来搭建MySQL数据库服务。这种方案门槛低，对于非数据库专业人员也能秒级搭建好一条MySQL服务。
搭建步骤
拉取MySQL数据库镜像
docker pull mysql:latest直接执行这个命令，意思是拉取最新的镜像，但是实际项目可能需要制定的数据库版本，所以这里需要制定标签，拉取需要的镜像
docker pull mysql:5.7.28 创建MySQL容器
拉取好镜像之后，就可以创建2个MySQL容器了，对外访问端口为3306,3307
[root@localhost ~]# docker run --name my -e MYSQL_ROOT_PASSWORD=root -p 3306:3306 -d -it mysql:5.7.28 423e39a1c8669a53942aed14002102adbb8871c47edfbaa67825691eb16d0d45 [root@localhost ~]# docker run --name my -e MYSQL_ROOT_PASSWORD=root -p 3307:3306 -d -it mysql:5.7.28 ff668e421d59b1fef61d58b70532bf87d5915da1c47d63db690857d74d283e12 [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ff668e421d59 mysql:5.7.28 "docker-en鈥 29 seconds ago Up 27 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp my 423e39a1c866 mysql:5.7.28 "docker-en鈥 About a minute ago Up About a minute 0.0.0.0:3306->3306/tcp, 33060/tcp my这样2个容器就创建好了，只是用docker ps显示的结果被截断了，不够友好，可以用下面的命令，来展示你需要看到的列信息就好
[root@localhost ~]# docker ps --format "table {{.ID}}\t{{.Image}}\t{{.Names}}\t{{.Ports}}\t{{.RunningFor}}\t{{.Status}}" CONTAINER ID IMAGE NAMES PORTS CREATED STATUS ff668e421d59 mysql:5.7.28 my 33060/tcp, 0.0.0.0:3307->3306/tcp About a minute ago Up About a minute 423e39a1c866 mysql:5.7.28 my 0.0.0.0:3306->3306/tcp, 33060/tcp 2 minutes ago Up 2 minutesMySQL服务测试
验证端口
[root@localhost ~]# netstat -an|egrep "3306|3307" tcp6 0 0 :::3306 :::* LISTEN tcp6 0 0 :::3307 :::* LISTEN 可以看到，3306和3307端口已经开启。
MySQL客户端连接测试
[mysql@localhost ~]$ mysql -uroot -proot -h 192.168.17.128 -P 3306 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor.
